Modified Rankin Scale
Records global functional disability after a neurological event, from 0 to 6.
When to use
Standard record of the functional outcome after stroke or another neurological injury.
Pearls and pitfalls
- The scale runs from 0, no symptoms, to 6, death, with one grade per level of disability.
- A favourable outcome is often described as 0 to 1 or 0 to 2, so record the exact grade, not the category.
- The scale measures global disability and does not replace an assessment of function per specific activity.

Formula
Grade from 0 to 6 chosen from the functional examination, with no calculation.
Evidence
